WootWoot, I'll see what I can do here quickly, and I'm sure a couple of our other well-versed forum denizens will have some ideas as well.
First, I'm a bit unclear as to how much you're paying on your home phone as it reads as though you're paying $70 for two cell phones and $15 for the internet, but no other price points have been cited as reference to the balance. Apologies if I'm being daft.
First question would be how much the internet would increase if you dropped the land line, as I'm guessing that price is dependent upon bundling the services. Odds are, the differential in price between picking up a VoIP provider like VOIPo and the increase in the internet cost should still be less than paying for both the internet and land line currently. In case the internet spikes considerably higher cost-wise, look into third party dry-loop (DSL without phone) Verizon DSL providers like
DSLExtreme. With a one year contract, their 3Mbps service is $25+tax a month, $35+tax without. Ideally, if you can get Verizon to provide that speed at those prices or less without a phone line, stay with them if possible as it's usually easiest to deal with the owners of the copper coming into your house for line quality issues than through a third party.
If you do migrate over to a VoIP home line plus third party DSL provider, keep in mind to port the home number out first before switching DSL providers, as third-party DSL providers nearly always have to re-re-provision after the phone service gets yanked, and that costs extra money and/or might be viewed as a premature contract termination... so plan ahead in that regard. Another thing to check before doing so is the quality of the internet service you're receiving before making the plunge into VoIP... utilize
speedtest.net and
pingtest.net to check your connection speed and quality as well as learn to properly configure your router to best serve your VoIP provider that you choose for optimal call quality. I like VOIPo for their 30 day trial period and ability to port your number over
after establishing service as it gives you the opportunity to bail out if your internet connection sucks. Utilizing a VoIP provider for your home phone will help tackle your dependence on your cell phones, though, as 5000 minutes on nearly any reasonably priced VoIP provider will be cheaper than any cell phone package, even "unlimited" ones.
As for the cell phones themselves, best to start with
examining the bills to see exactly what you're using per month on average, and figuring out how much of that usage might be successfully moved away to your new low-cost VoIP call provider. The remaining balance of minutes/texts/etc. can then be more easily tackled. Coming off Verizon,
PagePlus might be your easiest transitional move as you can port both your phones and your numbers over easily so long as you're either not under contract or you bought your contract out with Verizon before the transfer. Their "The 12" plan is kinda popular amongst the mustachians, but their "Talk 'n Text 1200" isn't terrible for the price either for that usage tier, and are pretty competitive cost-wise with
Ting for that level of service. Additionally, PagePlus' standard prepaid minute cards can be bolted onto the account and the balance kept rolling on top of your monthly plan to absorb any overages. Only major gotcha with PagePlus to keep an eye out for is their roaming charge fees, so make sure your phones are never roaming if you make a call.
In your case if you're wanting to completely drop your cell phone to keep costs low, but don't want to give up the convenience of having one for emergencies and aren't hardcore enough to go the deactivated handset for emergency calls with ARN to call AAA route that I proposed in the
cell phone portion of the guide... there's a middle ground called
PlatinumTel. You'll have to pick up one of their phones, but you can keep the service on life support for about $3.35 a month using their Real PayGo service, which will give you roughly 66 minutes or 165 SMS messages or 33MB of data (or some combination there-in) to play with a month. You just need to make sure you keep some sort of activity going within a 60 day window to keep the service active... fortunately, that's pretty easy to do these days between the occasional spam text message and background data usage with smartphones. Enough minutes and data to be useful in a month without costing an arm and a leg, and cheap enough to not feel an obligation to actually use it. They're even running an excellent loss-leader special currently with a
Sanyo SCP-3810 feature phone that gives you the phone and $50/6months of airtime credit for
$40. Bam! Cameraphone for no investment and under $3.50 a month to maintain.
Overall though, you're really not doing too terribly for what you're getting if your home phone service is costing you less than $25-30 a month. There's room for improvement, sure, but not quite as much as you might think across the board. The biggest place where you can cut costs will be with your cell phones, followed with home phone. Hope this helps to get you started!
